A. Outputs are decided through a process of negotiation during the software development process
B. Specification, design, implementation and testing are interleaved
C. Iteration occurs within activities
D. All of the mentioned

Explanation: A plan-driven approach to software engineering is based around separate development stages with the outputs to be produced at each of these stages planned in advance.

A. Incremental Development
B. Iterative Development
C. Linear Development
D. Both Incremental and Iterative Development

Explanation: The software is developed in increments with the customer specifying the requirements to be included in each increment and the highest priority is to satisfy the customer through early and continuous delivery of valuable software. They are iterative because they work on one iteration followed by improvements in next iteration

A. Spiral Model
B. Waterfall Model
C. Rad Model
D. 4GT Model

Explanation: Since coding phase is eliminated in 4GT Model,more expertise is required for analysis,design and testing activities.

A. Individuals and interactions
B. Working software
C. Customer collaboration
D. All of the mentioned

A. Improved productivity of software engineers
B. Reduction in software development time
C. 4GT helped by CASE tools and code generators offers a credible solution to many software problems
D. None of the mentioned

Explanation: Since automated coding is done using CASE tools & code generators proponents claim a dramatic reduction in software development time

A. on Lisp machine
B. on report generators
C. from database query languages
D. from GUI creators

Explanation: Fifth-generation programming language are built on LISP.

A. WINWIN Spiral Model
B. Spiral Model
C. Concurrent Model
D. Incremental Model

Explanation: When applied to client/server applications, the concurrent process model defines activities in two dimensions: a system dimension and a component dimension.Thus Concurrency is achieved by system and component activities occurring simultaneously and can be modeled using the state-oriented approach.

A. Doesn’t work well for smaller projects
B. High amount of risk analysis
C. Strong approval and documentation control
D. Additional Functionality can be added at a later date

Explanation: All other options are the advantages of Spiral Model.

A. diagonal, angular
B. radial, perpendicular
C. radial, angular
D. diagonal, perpendicular

Explanation: The radial dimension of the model represents the cumulative costs and the angular dimension represents the progress made in completing each cycle. Each loop of the spiral from X-axis clockwise through 360o represents one phase.

A. Build & FIX Model & Waterfall Model
B. Linear Model & RAD Model
C. Linear Model & Prototyg Model
D. Waterfall Model & RAD Model

Explanation: Each linear sequence produces a deliverable “increment” of the software and particularly when we have to quickly deliver a limited functionality system.
